app_store_versions__build__get

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, which the description aligns with by using 'Read'. However, the description adds no extra behavioral context beyond what the annotations provide, such as authentication needs or limitations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence plus the HTTP path, with no redundant or wasted words. It is efficiently front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read operation with good annotations, the description is nearly complete. It explains the action and resource. However, it does not mention the return value (e.g., a build object), which would be helpful given no output schema. Still adequate for the tool's simplicity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with a single parameter 'id' described as 'Resource identifier.' The description does not add any additional meaning or usage detail beyond the schema, so a baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb 'Read' and resource 'build for an App Store version', clearly distinguishing it from siblings like 'builds__get' which reads a build by its own ID, and 'app_store_versions__build__set' which sets the build. The HTTP method and path are included for additional clarity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description states what the tool does but does not provide guidance on when to use it versus alternatives (e.g., when you have an app store version ID and need the associated build, rather than using 'builds__get' with a build ID). No when-not or explicit alternatives are mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
